Relating electrolyte leakage to shelled corn storability
1998
Marks, B.P. | Stroshine, R.L.
Corn from three growing seasons was harvested, dried, and stored in small bins. Samples taken at harvest and after various periods of bin storage (up to 77 months) were evaluated by two primary tests: carbon dioxide evolution during accelerated storage at approximately 20.5% moisture content and 26 degrees C and electrolyte leakage from bulk (100 g) samples soaking in deionized water. The initial (t < 72 hr) slope of carbon dioxide evolution rate curves (SLOPE72) was used as a base measure of storability (i.e., potential for safe storage without significant mold invasion). In electrolyte leakage tests, both test temperature and initial sample moisture content influenced results. Additionally, water conductivity after 10 min was correlated (r = 0.79) with SLOPE72, implying that electrolyte leakage has the potential to provide rapid information regarding future storability
